icnsoonrive MACHINE- i Be it known that l, SAMUEL B. RAYZOR, citizen ofthe United States, residing at lDeliton, inv the county of Denton and State of Texas, have invented certain new and useful Improvements in lice-Scoring Machines, of which the following is a specification.l

rhis invention relates to machine for scoring cakes of ice preparatory to breaking same up into smaller cakes, and the primary object thereof is to provide a machine of this type which eects positive scoring of the ice by i'irst moving same in one direction and then in a direction at right angles to the irst direction, the iirst movement effecting scoring of the top and bottom faces of the ice and the second movement effecting scoring of the opposite side faces of the cake,l all of the scoring actions being effected by movement of the cake of ice in the same horizontal plane, thereby to eliminate all violent movements of the cake,

The invention further aims to provide a machine of this type which eliminates all movements of the ice other than in a common plane during all of the scoring actions thereon and which particularly avoids vertical or turning movements of the ice7 thereby to prevent likelihood of wastage by chipping or breaking up of the ice.

Still further, the invention aims to provide a novel manner of scoring of the ice cakes so that the latter can loe easily and quickly broken up into smaller cakes and with a minimum or wastage. l

Still further, the invention aims to provide a machine of this type which effects easy, quick and positive scoring of the ice cakes so as to aiford an increased capacityv for the machine.

Further and other objects will be later set f cured therctojvhich latter through sprockets and chain ll drive'sa `shaft 6' carrying vertical saws'7 5 and a pulley *6... Pulley 6 hasv a 'belt trained thereover, whichdrives a y pulley fi ons lower shaft S, 'the latter being' vertically. aimed with shaft 6a and carrying *cir-tical* sans S alinedVi withy saws 5.. The' trontsi eofjthe frame has a discharge opening on the oppositesides of'whichvertical shafts 11?' and 12i are journaled, the shafts carryinghorizontal saws 11 'and 12, which score the ice along the'lines e, e, as depicted in Figure e of the drawings. The shafts 11: and 12 are `driven in unison by sprockets and a chainlO", while the shaft 11Lv`is driven by sprockets and a chain 10 from a shaft journaled in brackets. a, a, and driven by bevel gear 9 on the shaft 6a. i

Conveyor means-,is employed to convey the ice cake 2 along horizontal guides 20, past the saws 5 and 8 including chains 1Ga trained over sprocketslt mounted on shafts llandl" that are journaled in the frame, the chains having stops or abutments 2Oe which engage the ice cake 2 to move the latter along the guides 20. Similar guides arev stop or abutment 191, past the saws 11 and 12. i sprocket 19 adjacent saws l1 and 12 has one end of chain 18 trained thereover, while a similar sprocket 18 mounted on a shaft 17' has v.the opposite end of the chain trained thereover. Shaft 17a is driven by bevel gear 1'? which is oaerated by asimilar gear on shaft 16". A shaft- 13a is driven from shaft 6% by bevel gearing andthrough a' worm drive 14- and 15 drives the shaft 16b and therebythe conveyor chains 16e. Side and end guides .2On and 2Ob respectively may be provided on the frame.

,ln operation the lcake of ice .2 is placed on the guides 2() and when chainsl move-the str/ps2()b into engagementwith the ice, the latter will be propelled along guides 20 and will be scored on the upper and lowerfsides thereof by the saws 5 and 8 forming the lines of'scoring al. shown in Figure 4. The

conveyorchains discharge the ice onto the right angular guides `and 'upon engagement thereof liv the stops 19 ofthe conveyor chain 13a the ice will be moved at right angles7 through the frame discharge and Will in such movement be scored along the lines e, Which latter scorings are of less depth than the scorings (Z. The ice is thus carried throughout in the same horizontal plane, avoiding` all agitating, 0r violent movements thereof likely to cause breakage or chipping of the cake.

lVhat is claimed is l. In a machine for scoring cakes of ice, vertical rotary saws for vertically scoring the calles on the top and bottom faces thereof, means for conveying the cakes in engagement with and past said saws means for receiving the cakes from the first named conveying means and for conveying .same at approximately right angles to the path of travel of the iirst named conveying means, and horizontal rotary saws for horizontally scoring the cales on opposite side faces thereof, the vertical sans and the horizontal saws being of such diameter and so arranged as to canse the vertical scores to be spaced from the horizontal scores and the latter' to opposite side faces thereofq the vertical scor! ing means and the horizontal scoring means being formed and arranged so as to cause the vertical scores to be spaced from the horizontal scores and the latter to be disposed between the inner sides of' the Vertical scores.

In testimony whereof I have signed my name to this specification.
